A new image compression algorithm, Distortion Limited Wavelet Image Codec (DLWIC), is introduced. The codec is designed to be simple to implement, fast and have modest requirement...
We propose a new algorithm for compressing three-dimensional triangular mesh data used for representing surfaces. We apply the EstimationQuantization (EQ) algorithm originally des...
Discrete wavelet transformations (DWT) followed by embedded zerotree encoding is a very efficient technique for image compression [2, 5, 4]. However, the algorithms proposed in l...
